Beamcast

Beamcast is a browser extension that turns the page you are already on into an AI workspace. Rather than asking you to copy text into a separate chat tool, it overlays a command layer on top of the web: highlight something, open the bar, and run a prompt in the same place you are reading. That design is aimed at people who live in tabs and find it disruptive to jump between a site and a chatbot dozens of times a day.

The extension focuses on the tasks that come up most often while browsing: summarizing a long article, rewriting a paragraph you plan to quote, translating a page in a language you do not read, or generating and explaining code while you read documentation. Because commands can be saved and reused, the tool rewards people who repeat the same workflows — a fixed summary prompt, a fixed translation pair — instead of retyping everything each time.

Beamcast is an independent third-party product and is not affiliated with OpenAI, Google or any model vendor whose name may appear in its listings. It works as a layer over the browser you already use and is distributed as a freemium extension, with the core commands available on a free tier.
